Data corruption is the accidental transformation of a file or the losing of information that often occurs during reading or writing. The reason could be hardware or software fail, and due to this fact, a file could become partially or fully corrupted, so it'll no longer function correctly since its bits will be scrambled or missing. An image file, for example, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. If such a problem appears and it is not identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file will be replicated on all the other drives and the harm will be long term. A number of widespread file systems either don't have real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Shared Web Hosting

We have resolved the problem of silent data corruption on all of our shared web hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems as it is the only one in existence which checks all of the files immediately by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in the event that any file is detected as damaged, it is replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the remaining SSDs. ZFS requires a lot of physical memory in order to perform the real-time checks and the benefit of our cloud website hosting platform is that we employ multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server plans, you will not have to worry about silent data corruption because we use ZFS - an advanced file system that checks all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems carry out checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a bad copy could be replicated on the other disks as well and you can lose important data. Because this is not the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
